A friend of mine said it snowed in Scottsdale also. Here in Surprise (west of Phoenix), it lightly snowed here too. All you could here is kids outside yelling out "It's Snowing!", as they ran around outside. The elevation here is about 1300 feet.
I still think Arizona has some beautiful weather. From the monsoon light shows (lightning over 1000 strikes), to the scary dust storms (habobs)that can raise dust 3000 feet. Just like in the movie The Mummy.
The last time I remember it snowing in Phoenix area was 1990. What a way to start the new year in Arizona!
